XML Billing Schema

This appendix provides a detailed description of the XML elements used in the XML billing records that the CUBE (SP) XML billing method generates, an XML billing sample file generated by the SBC, the termination codes for the XML billing records, and the XML Document Type Definition (DTD).

XML Elements Generated by CUBE (SP)

This section provides details of the XML elements used in the XML billing records that the CUBE (SP) XML billing method generates.

Attribute
Optional
Description

starttime

N

The time at which a call starts is the time at which signaling starts.

endtime

Y

The time at which a call ends is the time at which signaling ends and resources are released. This attribute is present if the call does not end, when the call detail record (CDR) is written. This is because the billing method instance is deactivated when the billingdeactivation element is present.

duration

Y

The length of the call, in milliseconds. This attribute is present if the call does not end, when the call detail record (CDR) is written. This is because the billing method instance is deactivated when the Billingdeactivation element is present.

The applicable values are as follows:

  • Orig—Indicates that the release is initiated on the originating side of the call.
  • Term—Indicates that the release is initiated on the terminating side of the call.
  • Neither—Indicates that the release is not initiated on either side of the call.

Omission of this attribute indicates that no information is available about the release initiator. One possible reason for this could be that the call is not yet released.
